    Jeep 4.0 in 69 Barracuda

    John; no chest-beating and, certainly no offense... Before I go completely silent on this subject (I have hijacked this thread, shamelessly, and that needs to stop,) I did not understand a couple of the things you said and if you will humor me this one time, I promise not to distract you from...

    Jeep 4.0 in 69 Barracuda

    John, I assume your answer to my question of, "How many turbocharged slant sixes have you worked on? How much information, in your experience, do you have about, what these forced-induction engines "like?" " is none, and none. Well, that is completely understandable, as the...

    Jeep 4.0 in 69 Barracuda

    John's First Comment "I am not one to follow the crowd. While my buddies were building v8’s (350’s, 360’s & 351’s), I built my race slant six which was good for an easy 13.9 second quarter mile. At some point I will build a stroker slant six. When I do that build, I don’t see the point of going...

    Jeep 4.0 in 69 Barracuda

    John, I know it's too late in this build to change anything; you are already well-past the point of no return and I understand that. Be that as it may, I was just curious as to why you chose the AMC engine to power this Barracuda when it entails so much adaptation and fabrication, not that...

    rarity of the 265?

    Get the right-sized turbo and the "lag" or, lack of low-end torque is no longer a problem. It's all about sizing.

    225 /6 at 250HP?

    But, research has proven that slant sixes with turbochargers run the best quarter-mile times with final drive gear ratios in the 2.76 range, so, there would be no need for an overdrive if you just geared the rear end like that. That "one size fits all" gearing would work for all kinds of...

    225 /6 at 250HP?

    That bolt appears to be in the piston, but, it's not... I machined a cylinder-size (less .010") piece if eighth-inch-thick aluminum to catch the shavings when I cut the O-Rings, so that when I was done cutting, I could just pull the aluminum piece out the top of the bore, and, the shavings...

    225 /6 at 250HP?

    Yes, that is the perfect carburetor for this buildup. Perfect! Use the modifications described in "Hangar 18" website and monitor the A/F ratio with you new O-2 meter and you'll be fine. Holley sells a 2-box set of jets (all sizes) to enable that. Get a set... The O-Rings are for...

    225 /6 at 250HP?

    This is a very interesting discussion with lots of possibilities... and, with several different ways to go. but, since it's YOUR car, you make all the decisions; I will offer what I think might work for you. The fact that you are only looking for a modeate amount of power (250 HP?) will make...

    Camshaft clearance

    IF that pump drag forces the cam rearward any time the engine is turning, then why would it be necessary or, even desirable to jerry-rig a cam button; it would never be used... would it? I am thinking, "if it ain't broke, don't fix it." What am I missing? And, to the OP, if you think your...

    new slant build cam choice help please

    Dan, I appreciate the information! My application is a "race car" only, and as such, is never driven in traffic. That allows me to get away with all sorts of things that would never work on the street.... primarily because this engine never sees much accrued mileage or hours of operation. I...

    new slant build cam choice help please

    Well, 252 is way too much duration for my motor, so it's very unlikely that I will be falling prey to that particular piece's mayhem, but I am curious about the Comp cam I DO have, wondering whether I should chance it, not knowing anything about the rear cam journal machining (how was it wrong?)...

    new slant build cam choice help please

    Dan, I am in possession of a new, still in the package, slant six cam, ground by Comp Cams. I want to try this cam because it has ten degrees more duration (220 vs 210@ .050"-lift) than the Bullet-brand cam that I am using in my turbocharged 225. I am really ignorant when it comes to cam...

    slant cam guessing game...428 lift?

    You may or may not know about this: Cam Doctor But, it would answer your questions and is interesting, I think. I had an "unknown" cam once and took it to my local (Fremont, CA) speed shop, and he happened to have a "Cam Doctor" in his possession. It answered all my questions about...

    rarity of the 265?

    Thanks! The transformation from grannie's grocery-getter to tire-smoking terror is quite dramatic. It's not that hard to put together a fun street machine with a turbo on a slant six, but, people seem intimidated by the "tuning" aspect of it. Too bad; it takes some patience, but pays off...

    rarity of the 265?

    "TURBO. (period) The /6 head is a big throttle valve stuck on low." I am glad to see that somebody "gets it" with regard to the slant six cylinder head issue. Though there have been countless examples of attempts by some pretty knowledgable hot rodders over the years to make a significant...

    How to I.D. the different /6's.

    The pertinent fact about this is: In the USA, EVERY SLANT SIX EVER BUILT, REGARDLESS OF DISPLACEMENT, had the same cylinder head. That means that the engines built with the 33% increase in displacement that occurred with the 170 becoming a 225, were equipped with the very same tiny ports and...

    Thanks for the nice comments! It makes about 360 horsepower (with a stock-sounding idle) on 15 pounds pf boost. It should run good on the street, but will never see the street, as it's just a motor to have fun with on the drag strip... Stock slant six A bodies usually can manage to run some...

    Here's my 225 with a 66mm turbo making 15 pounds of boost for about 350 horsepower. It lives in a '64 Valiant.

    What would you do? Slant performance

    Just got a flier in the mail from MO-KAN dragway that might be of interest to slant six fans who are in driving distance (it's near Joplin, Missouri.) The race is a special "race within a race" on Friday and Saturday, April 8th and 9th. There's a general MOPAR race on that Sunday, The...
